    摘要： An image reading apparatus includes a document table, a pressing plate that rotates about a rotation axis between an open position and a closed position, a line sensor that includes an image sensor arranged in a main scanning direction intersecting the rotation axis and outputs data by reading a document on the document table, and a control unit that determines presence or absence of the document based on first data acquired by the line sensor when the pressing plate is in an intermediate position before reaching the closed position and second data acquired by the line sensor when the pressing plate is in the closed position, wherein when the control unit determines the presence or absence of the document based on the first data and the second data, the control unit uses coefficient data that is smaller as a distance from the rotation axis is longer.

    摘要： An image forming apparatus includes a sheet accommodating portion that is attachable to and removable from an apparatus body and that is capable of accommodating a sheet therein; a detecting part that detects the presence/absence of a sheet in the sheet accommodating portion; a fixing part that fixes the status of detection by the detecting part to a sheet absent state when the sheet accommodating portion is not attached to the apparatus body; an informing part that informs a user of the status of the apparatus; and a control part that causes the informing part to inform the user of the possibility of a sheet left in the apparatus when the status of detection by the detecting part changes from a sheet present state to the sheet absent state during standby when printing is not performed.

    摘要： In image reading apparatus, reading control portion causes image reading portion to read at least line of image data when pivoting angle of cover member with respect to document sheet table has changed from angle exceeding predetermined detection angle to angle equal to or less than detection angle. Photoelectric conversion portion is disposed in area that is out of predetermined maximum readable size area in image reading portion, and is covered by cover member when cover member is closed. Data correcting portion corrects image data read by reading control portion, based on output of photoelectric conversion portion output when pivoting angle has changed from angle exceeding detection angle to angle that is equal to or less than detection angle. Document sheet width detecting portion detects width, in main scanning direction, of document sheet placed on document sheet mounting surface, based on image data corrected by data correcting portion.

    摘要： In an image-forming device, an image-reading unit reads an image formed on an original document. A data-reading unit reads data stored in a storing member of the original document. A duplication-performing unit performs a plurality of duplication processes including at least an image/data-duplication process in which the duplication-performing unit forms the read image on a first recording medium having a storing member and writes the read data to the storing member of the first recording medium, and a data-duplication process in which the duplication-performing unit writes the read data to the storing member of the first recording medium without forming the read image on the first recording medium. A receiving unit receives an image/data-duplication instruction and a data-duplication instruction. The duplication-performing unit performs the image/data-duplication process if the receiving unit receives the image/data-duplication instruction, and performs the data-duplication process if the receiving unit receives the data-duplication instruction.
